distal radial fractures (FRYKMAN CLASSIFICATION SYSTEM)

What frykman classification is this

Extraarticular fractures

○ Types 1 and 2:

What frykman classification is this

Intraarticular fractures involving the radiocarpal joint

○ Types 3 and 4:

What frykman classification is this

Intraarticular fractures involving the radioulnar joint

○ Types 5 and 6:

What frykman classification is this

Intraarticular fractures that involve both the radioulnar and radiocarpal joints

○ Types 7 and 8:

Kienbock’s Disease: What stage is this?

● Symptoms are similar to those of a wrist sprain

● Blood supply to the lunate has been disrupted

● X-rays may still appear normal or suggest a possible fracture

● MRI scan can better detect the effects of abnormal blood flow and is helpful in making the diagnosis in this early stage

● Parang sprain lang

Stage I

Kienbock’s Disease: What stage is this?

● Lunate bone begins to harden (sclerosis) due to the lack of blood supply

● Most common symptoms include wrist swelling and intermittent pain, particularly when force is applied to the wrist, such as with weightbearing

Stage II

Kienbock’s Disease: What stage is this?

The necrotic or dead lunate bone begins to collapse and fragment (break) into pieces

(Stage IIIA).

Kienbock’s Disease: What stage is this?

As the bone begins to collapse or break apart, the surrounding bones become affected and may begin to shift position

(Stage IIIB).

Kienbock’s Disease: What stage is this?

● The abnormal forces through the wrist due to the collapse of the lunate and shifted position of the other carpal bones result in arthritis of the wrist.

● Patients typically experience wrist pain, weakness in gripping, and limited wrist motion.

Stage IV

Doyle’s Classification of Mallet Finger Injuries:

Closed injury, with or without small dorsal avulsion fracture

○ Type I

Doyle’s Classification of Mallet Finger Injuries:

Open injury (laceration)

○ Type II

Doyle’s Classification of Mallet Finger Injuries:

Open (deep abrasion involving skin and tendon injury

○ Type III

Doyle’s Classification of Mallet Finger Injuries:

Mallet fracture

○ Type IV

Doyle’s Classification of Mallet Finger Injuries:

Distal phalanx physeal injury in children

○ Type IV-A

Doyle’s Classification of Mallet Finger Injuries:

Fracture fragment involving 20% to 50% of the articular surface

○ Type IV-B

Doyle’s Classification of Mallet Finger Injuries:

Fracture fragment involving more than 50% of the articular surface

○ Type IV-C
